Q: why is Nutri-Score is not calculated for this product?
A: There are many cases:
- some products are excluded from the Nutri-Score computation, such as baby food, coffee, tea, etc.
- the product is not categorised: Nutri-Score computation is based on categories; no category, no Nutri-Score
- the product needs ALL these data to be calculated: energy, fat and saturated fat, carbohydrates and sugar, proteins and salt. Sometimes the producer doesn't print these data because there are only traces. For example, many syrups don't print anything about fats, proteins and salt.
- some products need values for the prepared product: syrups, teas, coffees, ...
